We have applied the flea medication and now the fleas are dead, but Sidney is still bothering his belly where the flea bites are healing. It's not terrible inflamed or anything, but he keeps licking the healing bites. Is there a topical lotion or spray that you can recommend that can ease his skin while it continues to heal? Something that won't hurt him if he licks it off or will taste bad so he won't lick it? What do you recommend?
